         | is the direction the sun/moon rises and west is the direction
         | the sun/moon sets. One of the fascinating things I learned
         | about antiquity is they would often orient their maps so east
         | (the direction of the rising sun) was at the top of the map.
         | They didn't have magnetic compasses so there wasn't anything
         | special about north to cause them to orient their maps in that
         | direction.

               | 
               | Agreed that the belt is better from the standpoint of
               | what the device is for, but I think the anklet is a bit

         | When I was in the Navy as an Officer of the Deck (OOD), I used
         | to be able to visually measure distances on flat water in the
         | range of ~500 yards to a mile within a few tens of yards
         | because I had an internal sense of how big objects were and how
         | they would look at those ranges. This was because I constantly
         | had to measure ranges on radars and via moboards[0] when I was
         | a OOD-in-training and so I learned quickly how to measure
         | distances visually.
         | 
         | I also learned how to estimate how a ship was moving in ports
         | and transit canals and how to adjust that using engines simply
         | by looking around, much like you can adjust how you walk on a
         | surface depending on senses from your whole body about what
         | type of surface it is, how stable it is, etc. On gravel, most
         | people can sense a bit of slippage as they walk from their
         | feet, they might sense their body alignment from feet to head
         | moving slightly due to that slippage, etc. and all those senses
         | are used to tell "I need to slow down here" or whatever. For
         | ships, you get an idea for what direction the bow and stern are
         | moving, how they relate to your control angles, how that
         | relates to what you see around you, and also integrates your
         | body senses, because your body is a finely-tuned acceleration
         | sensing machine.
         | 
         | Anyways, I wish I were still an OOD today, because I would try
         | and create some tools like this that would help me there. Even
         | this anklet itself would have been helpful when I was on duty,
         | to tell me when the helmsman was asleep!

           | I wouldn't've thought of this, but of course that's critical
           | to know on a ship. And it's certainly something outside of
           | standard human experience, since we're small enough in that
           | dimension to not have to worry about the difference in
           | movement between our front and rear sides. The fact that you
